Molecular function

1,4-alpha-D-glucan:1,4-alpha-D-glucan 4-alpha-D-glycosyltransferase activity, D-enzyme activity, amylomaltase activity, debranching enzyme maltodextrin glycosyltransferase activity, dextrin glycosyltransferase activity, dextrin transglycosylase activity, disproportionating enzyme activity, oligo-1,4-1,4-glucantransferase activity

Catalysis of the transfer of a segment of a (1->4)-alpha-D-glucan to a new 4-position in an acceptor, which may be glucose or (1->4)-alpha-D-glucan.
